GENERAL SAFETY PRECAUTIONS
WARNING:
As with all machinery, there are certain hazards involved with their
operation and use. Exercising respect and caution will considerably
lessen the risk of personal injury. However, if normal safety
precautions are overlooked or ignored, personal injury to the
operator or damage to property, may result.
1. ALWAYS Learn the machines’ applications, limitations and the specific
potential hazards peculiar to it. Read and become familiar with the entire

replaced. If in doubt, DO NOT use the machine. Consult your local dealer.
4. ALWAYS disconnect the tool/machine from the power supply before
servicing and when changing accessories.
5. ALWAYS wear safety goggles, manufactured to the latest European Safety
Standards. Everyday eyeglasses do not have
impact resistant lenses, they are not safety glasses.
6. ALWAYS keep work area clean. Cluttered areas
and benches invite accidents.
7. ALWAYS ensure that adequate lighting is available.
A minimum intensity of 300 lux should be provided.
Ensure that lighting is positioned that you will not be

20. NEVER use power tools in damp or wet locations or expose them to rain.
Keep your work area well illuminated. Do not use in explosive atmosphere
(around paint fumes, flammable liquids etc). Avoid dangerous
environments.
HELPFUL HINTS ON DRILLING
• After drilling material to the full depth, do not simply pull out the drill but
maintain chuck rotation to ease withdrawal.
• Keep drill bits sharpened for optimum performance.
• Always drill directly in line with the bit. Do not use sideways movement as
this may damage the drill or cause the bit to break.
• Always use a cutting lubricant when drilling all metals except brass and
cast iron which should be drilled dry.
• As a general rule, when drilling metal, the harder the metal the slower the
drill speed. Similarly, the bigger the drill the slower the speed. Consult a
suitable book of reference if necessary.
• Always start drilling at a slow speed to prevent the drill from slipping out of
the pop mark or indent, gradually increasing speed until the optimum
cutting speed is achieved whilst maintaining a MODERATE pressure ONLY.
NEVER force the drill bit into the work. This will overheat the tip and cause
it to dull very quickly.

OPERATION
DRILLING TIPS
• Always use sharp, good quality drill bits. The performance of your drill is
dependant on the quality of the bits used.
• Reduce the pressure on the drill bit when it is about to break through. This
will prevent the drill from jamming.
• If drilling a large hole, first drill a pilot hole using a smaller drill bit.
• Always apply pressure to your drill bit in a straight line and, where
possible, at right angles to the workpiece.
• When drilling holes or driving screws into walls, floors etc., always make
sure that there are no live electrical wires in the path of the bit.
• When drilling in metal, the materials being drilled can become hot. To
reduce overheating use a suitable cooling lubricant. No cooling
lubricant is necessary when drilling cast iron or brass as they should be
drilled dry.
• To prevent the drill bit from slipping when starting to drill a hole in metal,
use a centre punch to make an indentation at the start point.
• When drilling in wood, clamp a piece of scrap wood to the underside of
the material to avoid splintering.
• Large holes should be drilled with wood augers, flat wood bits or hole
saws.
SCREWDRIVING TIPS
• Place the screwdriver bit in the head of the screw and apply light
pressure to the drill.
• Start the drill slowly and then gradually increase the speed.
• Release the trigger switch when the clutch operates.
• If the screw head is not flush with the material, increase the torque by
adjusting the torque setting ring and start again.
• Make sure that the screwdriver bit is inserted straight and upright in the
screw head, or the screw may be damaged.
• When driving wood screws, pre-drill pilot holes to make driving easier and
to prevent splitting the material.
• Select the forward direction to drive screws in and reverse direction to
take them out.
